Resumo(s)
Este estudo foi realizado para avaliar a situação sanitária das abelhas adultas nas diferentes ilhas com atribuição de estatuto de indemne sabendo-se que, em Portugal, seis das nove ilhas do arquipélago dos Açores (São Miguel - SML, Santa Maria - STM, Terceira - TER, São Jorge - SJZ, Graciosa – GRC, e Corvo) foram reconhecidas pela União Europeia como indemnes de Varroose (SRAF, 2019). Pretendeu-se também detetar parasitas menos observados atualmente na atividade apícola, tais como Acarapis woodi e Braula coeca, pesquisando igualmente a presença de Nosema spp., Senotainia tricuspis e Varroa destructor. Obteve-se no total 92 amostras das ilhas indemnes de Varroose, com exceção da ilha do Corvo, e determinou-se a prevalência anual dos diferentes agentes para cada ilha e mensalmente. Como expectável, não foi detetada Varroa. A prevalência mensal de A. woodi foi de 50% em junho (1/2), 48% em abril (14/29), 21% em setembro (7/33), 19% em julho (3/16) e 0% em outubro e agosto (0/11,0/1), considerando que SJZ teve 57% (20/35), TER 17% (1/6), SML 11% (4/36), STM e GRC 0% (0/8,0/7). A prevalência mensal de B. coeca foi de 81% em outubro (9/11), 39% em setembro (13/33), 31% em julho (5/16), 17% em abril (5/29) e 0% em junho e agosto (0/2,0/1). Na totalidade de amostras, GRC demonstrou 86% (6/7), 63% em STM (5/8), 50% em SML (18/36), 9% em SJZ (3/35) e 0% em TER (0/6). Nosema spp. teve100% de prevalência em junho (2/2), 76% em abril (22/29), 44% em julho (7/16), 33% em setembro (11/33), 27% em outubro (3/11) e 0% em agosto (0/1). No período de recolha de amostras, a ilha SJZ demonstrou a prevalência de 80% (28/35) de Nosema spp., com 71% em GRC (5/7), 28% em SML (10/36), 17% em TER (1/6) e 13% em STM (1/8). Senotainia tricuspis teve a prevalência de 50% em junho (1/2), 45% em setembro (15/33), 41% em abril (12/29), 19% em julho (3/16), 18% em outubro (2/11) e 0% em agosto (0/1)...
This study was carried out to assess the health situation of adult bees on the different islands that have been granted free status, knowing that, in Portugal, six of the nine islands of the Azores archipelago (São Miguel - SML, Santa Maria - STM, Terceira - TER, São Jorge - SJZ, Graciosa - GRC, and Corvo) have been recognised by the European Union as Varroa free (SRAF, 2019). The aim was also to detect parasites that are less commonly seen in beekeeping, due to the treatments carried out for V. destructor, such as Acarapis woodi and Braula coeca, while also investigating the presence of Nosema spp, Senotainia tricuspis and Varroa destructor. Obteve-se no total 92 amostras das ilhas indemnes de Varroose, com exceção da ilha do Corvo, e determinou-se a prevalência anual dos diferentes agentes para cada ilha e mensalmente. As expected, Varroa was not detected. The monthly prevalence of A. woodi was 50% in June (1/2), 48% in April (14/29), 21% in September (7/33), 19% in July (3/16) and 0% October and August (0/11,0/1), considering that SJZ had 57% (20/35), TER 17% (1/6), SML 11% (4/36), STM and GRC 0% (0/8,0/7). The monthly prevalence of B. coeca was 81% in October (9/11), 39% in September (13/33), 31% in July (5/16), 17% in April (5/29) and 0% in June and August (0/2,0/1). In all the samples, GRC had 86% (6/7), 63% in STM (5/8), 50% in SML (18/36), 9% in SJZ (3/35) and 0% in TER (0/6). Nosema spp. had 100% of prevalence in June (2/2), 76% in April (22/29), 44% in July (7/16), 33% in September (11/33), 27% in October (3/11) and 0% in August (0/1). During the sample period, SJZ Island a prevalence of 80% (28/35) of Nosema spp., with 71% in GRC (5/7), 28% in SML (10/36), 17% in TER (1/6) and 13% in STM (1/8). Senotainia tricuspis had the prevalence of 50% in June (1/2), 45% in September (15/33), 41% in April (12/29), 19% in July (3/16), 18% in October (2/11) and 0% in August (0/1)...
